CORIMA is a world leading company in the design and the manufacturing of high performance composite parts. In 1998, Corima puts its technical skills into the manufacturing of wheels and bike frames. CORIMA’S know-how is unique and our company is well known for its constant innovation. Innovations that involved a real revolution of all the materials in all the cycling disciplines.
In this very competitive market, it’s the quality and the innovation of the CORIMA products that establish the worldwide reputation of the brand. Due to our experience in working with composite materials, we control all of the steps in the manufacturing process to make your product “unique”: the design, the production, the control and the after-sales service, everything being made in our plant in Loriol sur Drôme in France.
At CORIMA, we place a great deal of importance on the aerodynamic performance of our wheels. Over 20 years ago, we developed a high-performance composite DISC wheel. In 1993, Chris BOARDMAN used our equipment, frame and wheels to achieve the most symbolic of records in technological terms.
Since then, we have constantly innovated to maintain our lead, and this has made the CORIMA range of wheels the most sophisticated in the world for aerodynamics, which is so vital to the cyclist’s performance.
Our experts carry out computer simulations to constantly try and reduce drag. This research involves optimising friction pressure on the various surfaces of the wheel and tyre. We also work to improve the air flow speed and air flow separators on the wheel to obtain a wheel that requires as little power as possible to move forward and spin.
We have designed dozens of prototypes and repeatedly cross-referenced the precise results achieved by our various models on our test benches. When we then validate our best projects in the wind tunnel, we know that the hours of experience that we have accumulated and the use of the most sophisticated technologies make our wheels unique in the world.
CORIMA Concept 2D
The latest aerodynamic research carried out in our research centre has led to a new rim design that we call Concept 2D. This new shape improves air flow and increases the rigidity of the tubular rim.
Concept 2D, which was first used on the 3 Spoke carbon wheel, which is positioned as the best suited wheel to the triathlon and time trials, has now been transposed to the Disc, VIVA “S”, UP “S”, AERO+, WINIUM+ and MCC wheels.
3D-CAD : The mastery of optimization on virtual models, 3D CAD design.
Tooling: The ability to design and produce all the moulds, tools and special machines required to properly implement the manufacturing process.
This global experience allows us to offer you a range of products of excellent quality and very good value for money.
Design : In the development of a product, we determine the technical specifications, where we include both our sales department and our customers to clearly understand the product requirements then arrives the phase of conceptual design of the product as well as the design of the production process. We design our own machines to make the products. This allows us to control the process and to respond quickly to repair, maintenance and quality issues.
Production / Controls
All of our products are manufactured at our plant in Loriol sur Drôme (26) in France and are carried out by our qualified, skilled and attentive personnel.
To achieve its desired level of performance, CORIMA has chosen to manufacture its prorducts from pre-impregnated carbon sheets and fibres.
Each pre-impregnated part has to be put in position, ensuring that the fibres are correctly orientated in a vital, determined order and with a strict eye on the quality procedure.
We have the ability to design and produce all of the assemblies and machines to check the quality and characteristics of the manufactured parts and to ensure the tracking of each manufactured part.
CORIMA products are exported in more than 70 countries.
All our spoked wheels are hand-built. The rear AERO+, are built with 20 spokes whose positioning in the rim was very well studied.
The drive side (cassette side) is built with 12 spokes crossed 3 times, a setting that has proven over the years to provide the best transmission of power from the cy- clist to the driving wheel. The left side of the wheel is built with 8 spokes.
This arrangement allows for a more uni- form tension across all of the spokes. This makes the wheel faster providing excellent stiffness. It also improves the wheel’s ability to remain running “true” and in- creases the spokes durability.
In addition, this specific spoke arrangement gives the rear wheel a very modern and technical look.
CORIMA has been designing its own hubs for more than 20 years.
The hub is very important on a wheel and it must be designed in the same time of the composite part (rim) in order to optimize the product.
Developed by our design office, our aluminum hubs are made in France from the best alloys by precision engineering specialists using the most up-to-date machining equipment.
The “S” version in chromeplated aluminium benefits from the latest innovation with, for example, a 30-tooth free-wheel ratchet ring and a Ø 17 mm titanium/aluminium spindle.
The carbon model is made with an exclusive moulding technique combining strength and lightness with an exceptional finish.
CORIMA hubs are also fitted with top of the range cartridge bearings.
